Custom RF Test Fixtures

Custom RF Test Fixtures provides high-isolation testing environments engineered to protect sensitive wireless devices from external electromagnetic interference (EMI) and radio frequency interference (RFI). Because modern wireless modules demand rigorous, isolated validation, every fixture is completely customised to meet the specific frequency requirements, attenuation targets, and mechanical constraints of your project.

Developed through the joint expertise of Columbia Elektronik and Columbia Mekan, these fixtures combine heavy-duty shielding architectures with high-performance internal electronics. By creating a dependable, repeatable testing environment, our solutions ensure your wireless assemblies are evaluated accurately without signal leakage or environmental distortion.

Key Features & Technical Highlights

• Superior RF Shielding & Isolation: Built using robust metal enclosures lined with premium RF-absorbing foam and high-grade conductive gaskets to deliver exceptional signal attenuation across a wide frequency spectrum.

• Project-Specific Internal Nesting: Custom-machined, non-conductive mechanical nests are designed for each unique board layout. These nests securely hold the device under test (DUT) and perfectly align it with specialised RF antennas or high-frequency coaxial probes.

• Filtered Interface Plates: The rear and bottom enclosures feature customisable interface panels equipped with filtered data connections (such as USB, DB9, and DB25) alongside high-quality coaxial RF bulkheads (including SMA and N-type connectors) to maintain complete shield integrity.

• Versatile Actuation Mechanisms: To match your specific production line layout and throughput requirements, the fixtures can be configured with smooth, high-locking manual lever assemblies, automated pneumatic cylinders, or precision electric drives.

• Multi-Protocol Compliance: Tailored to support a diverse range of wireless protocols, including Bluetooth, Wi-Fi, cellular (4G/5G), Zigbee, RFID, and custom sub-GHz or microwave applications.

Applications

This customisable RF platform is ideal for end-of-line (EOL) functional testing of IoT gateways, smart home devices, automotive telematics units, medical telemetry, and wireless communication hardware requiring strict signal isolation and precise validation.
